All fiber optic cable connections require single-mode Dual-LC type connectors.
Figure 34 shows the basic configuration of the optical path between the Hub SIF and the RAN
SIF. For optical specifications, refer to Table 2 on page 6.
Figure 34. Optical Path Between Hub SIF and RAN SIF
For fiber cable ingress, the RAN is equipped with a nylon fiber optic connector located on the
rear side of the cabinet. The connector accommodates cables of a diameter in the range .38 to
.50 inches (.97 to 1.27 cm).
Use the following procedure to install the fiber optic cable:
1. Route the connectorized end of the fiber optic cable from the splice enclosure (not
provided) to the rear side of the cabinet. Estimated length of cable is 30 feet (9 meters)
although this is dependent upon distance from the splice enclosure.
Note: If the installer has a larger cable, the manufacturer (Hubbell Inc.) makes bushings
that fit this connector in the following size ranges: .500-.625, .625-.750, .750-.875, .875-
1.00, 1.00-1.125 inches.
Note: The routing of an Outside Plant (OSP) fiber optic cable from the Hub to a splice
enclosure in the vicinity of the RAN cabinet and the splicing of selected OSP cable fibers
to the fibers in the outdoor-rated cable is the responsibility of the installer.
Warning: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation
can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not
look directly into the optical transmitter of any unit or exposure to laser radiation may result.
An optical power meter should be used to verify active fibers. A protective cap or hood MUST
be immediately placed over any radiating transmitter or optical fiber connector to avoid the
potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles
from entering the connector.
